Happy Pi Day! Here are 10 ways to show your appreciation for everyone鈥檚 favorite irrational number on March 14^th:

1.Make art聽

Create a , , or using the digits of pi 鈥� or use your imagination to come up with your own creation

2. Memorize it

is helpful if you鈥檇 like to learn more digits of pi 鈥� the most ever memorized by one person is 67,890! It took Chao Lu 24 hours and 4 minutes to recite with no breaks.

3. Record a video

Educate others by creating and editing a video like that shows off pi鈥檚 irrational nature and integrates math, design, and technology into one creative product.

4. Learn something new

Expand your pi day knowledge by learning about or with the .

5. Listen to (or compose!) music

The video demonstrates pi鈥檚 melody on a variety of instruments. Sit back and enjoy the harmonies or think of a new way to turn pi into melody using your own musical talents!

6. Read a story

is book two in the Sir Cumference Series, recommended for ages 8-12. In this installment, Radius must solve a math riddle in order to reverse Sir Cumference being changed into a fire-breathing dragon!

7. Write a poem

Similar in basic structure to a haiku, a 鈥淧i-ku鈥� has three lines of poetry: the first is three syllables, the second is one syllable, and the third is four syllables. provides more information and examples to get you started!

8. Bake something tasty

What better way to learn than by making something you can eat? Browse for a delicious pie, pizza, or other circular food recipe and then try to hold off on eating it long enough to calculate its area using pi! Remember, the area of a circle can be calculated using A = 蟺r² where r is the radius.

9. Sing a song

Math Geek Mama shares a free downloadable with songs set to the familiar tunes of Jingle Bells, Happy Birthday, and more!

10. Prove it!

How did Archimedes discover pi in the first place? Test pi with or read this of its existence.

With the fall season upon us, we here at 优蜜视频 would like offer a guide to festive fall activities for you and your family. But let us set the tone with inspiration from the poet John Keats.

鈥淭o Autumn鈥澛燽y John Keats

Season of mists and mellow fruitfulness,
Close bosom-friend of the maturing sun;
Conspiring with him how to load and bless
With fruit the vines that round the thatch-eves run;
To bend with apples the moss鈥檇 cottage-trees,
And fill all fruit with ripeness to the core;
To swell the gourd, and plump the hazel shells
With a sweet kernel; to set budding more,
And still more, later flowers for the bees,
Until they think warm days will never cease,
For summer has o鈥檈r-brimm鈥檇 their clammy cells.

Now that we鈥檙e inspired to indulge in the beauty and magic of Autumn, what better way to celebrate the season than with science, snacks and crafts!

Calling all fall-leaf-lovers:

1. with Scientific American

This project explores chromatography using fall leaves. Discover which pigments make up the beauty of fall!

2. Create with Mr. Otter Art Studio [maybe even embed this video?]

This video demonstrates how to make lovely leaf rubbing with a watercolor wash. Learn how to make

3. Fall leaves are truly one of my favorite things. Here are a few different ways to preserve them:
   1. Try with Tinker Labs
   2. Make a 鈥淲ax Dipped Leaf Garland鈥� with Leah McDermott
   3. Create with Creative Homemaking

How about some spooky science:

4. Explore 鈥溾�� with Amada Morgan

You will not be disappointed by these endlessly interesting opaque bubbles bursting with fog!

One of the best things about fall is the food! Here are some tasty treats to fuel your explorations:

5. Learn with Tinker Labs

Have you ever seen those dried cobs of corn in the market and wondered if they were food or just a decoration? Next time, pick one up, throw it in the microwave and wait for the magic!

6. Make with Yesterdish

This simple recipe is an exploration of perception, food science and American history all in one.

There are so many fun projects out there. Hopefully these activities will lead you on to many more festive explorations! What is your favorite fall-themed activity?

Science + crafts who knew?!

Look no further for a holiday craft bound to brighten the season. Below you鈥檒l find instructions for how to make a light up card using a simple circuit. Before we begin, here is a that will give you a glimpse of the project.

What you鈥檒l need:

• • Did you know ? This tape can be found at your local hardware store under the name 鈥渟lug tape!鈥�
• Cardstock or construction paper
• Tape
• Scissors
• Any and every crafting supply! (Including but not limited to: colored pencils, crayons, markers, tissue paper, glitter, felt, foam, and feathers)

Step I: Fold the card
Start with a full sheet of cardstock or construction paper and fold it in half to make a card.

Step II: Design your masterpiece
Think of how you would like to decorate the front of your card. What part of the scene would you like to be lit up, maybe a reindeer鈥檚 nose, the glowing part of a candle, a star, or lights on a tree? Whether you choose a figurative scene or an abstract universe, draw, cut and glue your heart out. Just don鈥檛 forget to pick a spot for the light!

Step III: Locate the light
Once you know where you want the light to appear, poke a small hole through the front panel of the card with a pen or scissors. On the inside flap of the card, use your pencil and draw a small circle around this hole.

Step IV: Map it out
Open up your card and follow the steps below to draw a map of the circuit directly behind your creation.

1. With a pencil make a medium circle where you want your battery to go. (Consider This: When the card is closed, you will press the battery to make the light come on. Put the battery in a place that correlates with your design. Like right on the stump of your Christmas tree for example.)
2. Now, draw lines to represent the copper tape
   1. Draw a line from the center of the battery circle to one side of your light hole (negative current).
   2. Beginning on the opposite side of the battery circle, draw a line to other side of the light bulb (positive current). Make sure your line does not touch the edge of the circle.

Step V: Where the magic happens

1. Lay the copper tape along the lines you drew in Step IV.
   1. Lay the copper tape over the first line you drew (from the middle of the battery to the edge of the light hole). This is the negative strip.
   2. For the positive strip, fold a half inch tab on one side of your copper tape. Right beneath the fold, lay the copper tape over the second line you drew (from the opposite side of the battery to the edge of the light hole). The tab should hover over the battery when you are finished. This will serve as your on/off switch when the card is closed.
2. Place the battery on your map negative side down. Secure the battery using clear tape. Make sure to only cover half of the battery with tape so that there is plenty of room for the folded tab to make contact with the positive side of the battery.
3. If you are using LED lights like the one鈥檚 linked above, there will be a short leg and a long leg (these are called leads). Push the bulb through the hole and tape the longer lead (positive) to the positive strip of copper tape. Now tape shorter (negative) lead to the negative strip of copper tape. Depending on what kind of LED light you have this part may look a little different.
4. Test your light by pressing the positive folded tab to the battery. Now, close the card and check it out.
5. Don鈥檛 forget to write a note!
